The commission says the Morgan Stanley business unit erroneously transferred $16 million from a customer’s account last year but fixed the error the next day. It also says that during 2012, the firm comingled customer and firm funds in a customer account, made errors in its daily computation of funds and improperly titled four of the firm’s accounts as customer accounts.

The company said in a statement Thursday that no customer lost any money as a result of the issues. It noted that it hired an outside auditor to review its procedures, and made required improvements.
